Description

Technical Field

[0001] The utility model relates to the technical field of circuit board processing, in particular to an exhaust gas treatment device. Background Art

[0002] A large amount of waste gas is generated during the production of circuit boards. These waste gases mainly come from various links in the production process, including the use of solvents, the process and the materials themselves. When the processing process requires heating, the waste gas generated is hot waste gas. Since the waste gas contains many harmful substances, the waste gas cannot be discharged directly into the air. It is necessary to use a waste gas treatment device to filter the harmful substances in the waste gas before discharging it.

[0003] In the prior art, there is a circuit board processing waste gas treatment device with announcement number CN221182181U, which includes: a box body, a partition is arranged inside the box body, a long opening is arranged in the partition, an exhaust fan is arranged on one side of the upper end of the partition, a dust collection box is arranged on the lower side of the partition, a straight plate is arranged on one side of the lower end of the partition, an exhaust gas treatment box is arranged on the other side of the straight plate, and a filtering mechanism is arranged on the side of the upper end of the partition away from the exhaust fan; by setting an air intake component, after moving the device to the use position, the handle on the upper end of the carrying connecting seat is used to align the air intake hopper at one end of the connecting seat with the exhaust gas generation position, and the connecting seat is adsorbed on the table by a suction cup. When the exhaust fan inhales air, the exhaust gas enters the box body through the air intake hopper, the hose and the fixed hopper for treatment. When the device is not in use, the connecting seat can be placed in a placement tray. By setting the air intake component, the exhaust fan can better suck the exhaust gas into the box, thereby improving the exhaust gas treatment efficiency.

[0004] However, in the above scheme, after the spray mechanism sprays the exhaust gas, the ash-water combination directly enters the dust collection box through the long opening of the partition. Since the capacity of the dust collection box is limited, in order to avoid the overflow of the ash-water combination in the dust collection box, the ash-water combination in the dust collection box needs to be cleaned frequently during the exhaust gas treatment process. When cleaning the dust collection box, the exhaust gas treatment device needs to suspend work, which results in a large number of shutdowns of the exhaust gas treatment device, affecting production. Utility Model Content

[0005] The utility model aims to provide a circuit board processing hot waste gas treatment device, which can reduce the number of shutdowns and avoid affecting production.

[0006] In order to achieve the above-mentioned purpose, a circuit board processing hot waste gas treatment device is provided, which comprises: a box body, wherein an air intake chamber, a spray chamber, a drying chamber and a waste gas treatment chamber are arranged in the inner cavity of the box body, wherein the air intake chamber and the drying chamber are arranged side by side and located at the top of the waste gas treatment chamber, and the spray chamber is located at one side of the air intake chamber, the drying chamber and the waste gas treatment chamber, and the air intake chamber, the spray chamber, the drying chamber and the waste gas treatment chamber are connected in sequence; an air intake component, wherein the air intake component is connected to the box body and connected to the air intake chamber; a spray chamber The spray assembly is located in the spray chamber, and the spray assembly includes a water tank, a filter bucket, filter cotton, a water pipe, a water pump, a diversion pipe and a nozzle.

[0007] The working principle and effect of the above scheme: when the device is used to treat the exhaust gas generated by circuit board processing, the end of the air intake component is aligned with the area where the exhaust gas is generated, and the air intake component pumps the exhaust gas into the air intake chamber. The exhaust gas passes through the air intake chamber to the spray chamber, and then the spray component works. The spray component can absorb dust in the exhaust gas and reduce the temperature of the exhaust gas. After passing through the spray chamber, the exhaust gas enters the drying chamber for drying, and finally enters the exhaust gas treatment chamber; when the spray component is working, start the water pump, and the water pump pumps the water in the water tank through the water pipe into the diversion pipe. The water in the diversion pipe is sprayed out through the nozzle and forms water mist that falls downwards. In the process of falling, the water mist absorbs dust in the exhaust gas and absorbs the heat of the exhaust gas. The water mist falls on the filter cotton, and the filter cotton can filter the dust in the water. The water filtered by the filter cotton flows into the water tank from the filter bucket.

[0008] By setting up filter cotton and water tank, the nozzle draws water from the water tank, and the water sprayed by the nozzle is filtered by the filter cotton and then drips into the water tank. In this process, the dust in the exhaust gas is adsorbed on the filter cotton, avoiding the need to frequently clean the gray-water combination in the water tank during the exhaust gas treatment process, thereby reducing the number of shutdowns and avoiding affecting production.

[0010] When the air intake assembly is working, place the air intake scoop in the working area and start the exhaust fan, which will draw the exhaust gas near the air intake scoop into the air intake duct through the hose and the pipe head.

[0011] According to the circuit board processing hot waste gas treatment device, a handle and a suction cup are arranged on the outside of the pipe head, and the handle is located above the suction cup.

[0012] By setting a lifting device, the pipe head can be taken by the lifting handle when the air intake assembly is working; by setting a suction cup, the suction cup can be adsorbed on the platform of the working area when the air intake assembly is working, and there is no need to manually hold the pipe head at this time, thereby saving manpower.

[0015] According to the circuit board processing hot waste gas treatment device, a waste gas filter plate is arranged in the waste gas treatment chamber.

[0016] By arranging an exhaust gas filter plate in the exhaust gas treatment chamber, when the exhaust gas reaches the exhaust gas treatment chamber, the exhaust gas filter plate absorbs harmful substances in the exhaust gas, thereby purifying the exhaust gas.

[0017] According to the circuit board processing hot waste gas treatment device, a baffle is provided on the inner wall of the spray chamber at the top of the water tank.

[0018] By arranging the blocking bar, when the water tank is placed at the bottom of the spray chamber, the blocking bar can limit the water tank from moving along the upper part of the spray chamber.
